AN8293SA, AN8293SC
Optical Disc Brush-less Spindle Motor Drive IC
Overview
The AN8293SA and AN8293SC are ICs for driving the
Optical Disc spindle motor. They employ three-phase full-
wave soft switch driving system, and do not require the capaci-
tor between motor windings (snubber-less). They are suitable
for miniaturized brush-less motor drive.
